IVIOTOR ATTACHMENT FOR CYCLES.

SPECIFICATION forming part of Letters Patent No. 709,549, dated September 23, 1902.

Application filed eptemher 20, 1901. Serial No. 75,777. (No model.)

To all whom it may concern:

Be it known that LLEONARD MEYRIOK MEY- RIOKJONES, engineer, a subject of the King of Great Britain, residing at Bawdeswell, East Derebam, in the county of Norfolk, England, have invented a certain new and useful Improved Means and Appliance for Enabling Motors to be Used with Bicycles and the Like, of which the following is a specification.

This invention has for its object the application of motors to bicycles and the like. This is effected by carrying the motor on a light frame which can he slid backward or forward along and be secured at any desired point to longitudinal slide-bars which are secured by clamps to the cycle-frame, or these bars might be movable backward or forward through the clamps or both together. The frame carrying the motor may be placed between two bicycles which are side by side and at a distance apart from one another. The motor may be mounted on a single trans verse bar having clamps at its ends to embrace longitudinal guide-bars, the ends of which are in turn held in clamps on short rods which by other clamps are secured to suitable members of the cycle-frames, the clamps at each end of this attachment being capable of turning to any required angle rela' tively to each other. Other stay-bars are similarly carried from the motor to the opposite ends of the cycle-frames or as otherwise required. The motor may be arranged to drive a transverse shaft, and pinions on the ends of this shaft may be made to gear with toothed wheels secured to the crank-axle or driving-wheels (either front wheel or back wheel) of the cycles.

It is not necessary that the two bicycles should be of the same size or construction.-

In these respects there may be considerable difference between them. Where required, the steeringgearof the two cycles may be coupled.

In place of the motor being carried by a single transverse bar a light open-trussed frame with clamps atits ends might be substituted for the bar.

Figure 1 is a side elevation, Fig. 2 a rear elevation, and Fig. 3 a plan, showing two bicycles connected together by a frame made according to my invention and carrying a motor which drives a shaft at the rear of the frame through a belt. Figs. 4:, 5, and 6 are similar views of a modified form of frame in which the motor is at the rear. Fig. 7 is a view showing to a larger scale one of the clamps for securing the frame to the bicycles.

In Figs. 1, 2, and 3, a a are two bicycles, to whose heads and backstays four rods (2 are secured by clamps b. Each .rod carries a clamp D which can be turned at any angle to the clamps Z) at the other end of its rod. This can conveniently be efiected by connect ing the clamps b to therods b by a screw thread of fine pitch, as shown in Fig. 7.

The clamps Z2 hold two longitudinal bars 0, each carrying a forward socket c and a rear socket 0 The forward sockets c carry a motor (1, which may be of any convenient pattern, while the rear sockets carry a transverse bar 6, provided with bearings e for a shaft f driven from the motor by a belt d and having at its ends pinions f gearing with special pinions a, provision being made for enabling the pinionsf to run at different speeds for turning corners, on the hubs of the back wheels of the bicycles a. The bearings 6 may be further supported by rods 6 fixed to the motor-casing.

In the modification shown in Figs. d, 5, and 6 the motor-frame instead of being fixed in sockets fast with the longitudinal bars 0 is carried by clamps 0 so that it can he slid along the bars. The motor cl also is at the rear of the frame and drives the shaftf by toothed gearingf while the motion of the shaftf is transmitted by belts or straps f to pulleys on the back wheels. 9 is a crosstie connected by rods g to the motor-casing.

\Vhat I claim is 1. The combination of two bicycles, a set of clamps engaging their frames, a second set of clamps adjustably carried by the first set, and a motor-frame carried by the second set of clamps.

2. In a motor attachment for cycles, the combination of a set of clamps engaging the bicycle-frames, a second set of clamps adjustably carried by the first set, longitudinal bars carried by the second set, a motor carried-by the longitudinal bars, a shaft driven by the the longitudinal bars, and means for driving motor, and pinions on the shaft engaging [O the bicycle-Wheels from the motor. pinions on the hubs of the bicycle-wheels.

3. In a motor attachment for cycles the T 1 combination of a set of clamps engaging the LEONARD MEYRIOK MEYRICK JOAES' bicycle-frames, a second set of clamps adj ust- Witnesses: ably carried by the first set, longitudinal bars FRED TAUDY HALL, carried by the second set, a motor carried by WALTER BENJAMIN SCOTT.
